To all whom it may concern:

Be it known that I, GEORGE H.

a citizen of the United Louisville, in the Surname, States, residing atnew and useful Improvements in Coin-Controlled Vending Machines; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to coin controlled vending machines, and itconsists of the novel construction, combination and arrange-'- ment ofparts hereinafter fully described and claimed, and illustrated in theaccompanying drawings, wherein Figure 1 is a view in front elevation ofvending machine constructed in accordance with my invention,

Corresponding and like parts are referred to in the followingdescription, and designated in the several views of the accorn panyingdrawings, by similar reference characters.

The casing of the vending machine comprises a bottom 1, a lower backsection 2,

movably retained in place integrally with the sides with a mirror sight;opening portions 3 an having upper portions 3 of L reduced width.

These parts together with a ojecting tray a are preferably e front 5 ofthe casing is reby lugs 6 formed 3, and is provided 7 and a horizontalrow of 8 closed by glass panels 9. carrier comprises a plate 10 rearedges of the side d which is provided at its inner s The article sidewith vertically extending angular members 11. plate provide Thesemembers together with the article receiving compartments 12 in frontsides of which are vertical slots The upp er portion of the plate 10constitutes the upper back section of the casing, and the lower portionthereof extends down-- wardly into the casing in forwardly spacedrelation with tion 2. A top 14 is secured to the edge of the plate 10 bycloses the upper partments 12.

respect to the lower back secupper hinges 15, and it ends of the casingand com- .A lock 16 carried by the front 5 and engaging the top 141prevents the unauthorized removal of the former and the unauthorizedopening of the latter. A door 17 resting upon the inclined upper edges18 of the sides 3, secured at its lower edge to the upper edge of thelower back section by hinges 19, and secured in closed position by athat free access may lock 20, is provided in order be gained to thedispensing mechanism of the machine for the purpose of inspection orrepair.

The machi the purpose ne is especially designed for of vending cakes ofsoap in factories, ofiices and the like, and the cakes of soap 21 arearranged ments 12 and ends of guides 22. A wardly extending within thecomparttherein by the front downwardly and forpartition 23 is securedsupported within the casing below the guides 22, and

is adapted to direct the articles pushed from the compartments 12 intothe tray 41. The

partition 23 24 to permit is provided with side flanges it to be boltedto the sides 3.

A coin receiving drawer 25 is located within the casing in rear of thepartition 23, and is removablethrough one of the sides 3. The drawer 25is slidably mounted upon the bottom 1 between guides 26, and is providedwith a lock closed positio 27 by which it is secured in n.

Each of the guides 22 comprises a plate 28 resting upon and bolted to arib 29 formed integrally with the lower back section 2 and a flange 30extending rearwardly from the upper end of the partition 23. The plates23 are provided with side flanges 31, the front portions 31 of which arehigher than their rear port-ions 31 The flange portions 31 are locatedwithin the lower ends of the compartments 12-and the articles 21 aresupported directly thereby. The plates 23 are provided vith openings 32located above the drawer 25 so that when a coin is released from one ofthe pushers 33 it will fall into the drawer. The pushers 33 are slidablymounted upon the plates 23 between the flanges 31, and are provided withcoin receiving slots 3t which gradual ly increase in width in thedirection of the lower sides of the p hers. The pusher-s '2 are providedwith horizontal grooves 35 which intersect the slots 3t and which openout through the ends thereof and receive coin stops 36. The coin stops36 prevent the passage of coins through the slots 3% until the pushers33 have been moved far enough to carry their slots 3t beyond the forwardends of the stops. When the pushers 33 reach this position the lowermostof the articles 21 will have been discharged from the compartments l2and the coins will pass through the slots 3d and openings 32 into thedrawer 25. The pushers 33 are yieldingly retained in retracted positionagainst stops 3'? by springs 38 secured to the pushers and lower backsection 2, and when in this position there coin slots 34 are partlyclosed by the stops 36. The pushers 33 are adapted to be moved forward1y by pulls 39 of U-shape. The side members 410 of the pulls 39 passthrough slots etl in the compartnient forming members 11 and lots 42 inthe front 5, the slots opening out through the lower ends of the partsin which they are formed in order to permit the removal of the articlecarrier and the front The inner ends of the pull members are connectedto trunnions which are carried by the pushers 33, and they are securedto the trunnions by cotter keys 4st. The cross members 45 of the pulls39 provide hand grips, and secured to the pull members 40 between thepull members t5 and the front 5 are cross pieces as which when thepushers 33 are in normal position contact with the front 5. The pushers33 are held against any but forward and rearward sliding movements onthe plates 23 by the flanges 31 and the coin stops 36.

A gravity actuating detent 4:7 is provided for each pusher 33. Thedetents 47 rest upon the pushers 33, and have their rear ends pivoted asat L3 to the lower back section 2, and are provided at their forwardends with depending hooks i9 which when the pushers 33 are in normalposition occupy a position slightly forward of the front ends of thepushers. The detents 4C7 extend over the coin slots 3t and are notchedas at 50 to accommodate the lower ends of coin chutes 51 whichcommunicate at their lower ends with the slots. In their under sides thedetents 1? are provided with cam portions which are arranged slightly inadvance of openings 53 in the front sides of the coin chutes 51. Duringthe initial phase of the forward movement of the pushers 33, the upperedges of the coins contact with the cam surfaces and raise the detents4-? far enough to carry their hooks out of the path of the carriers.After the coins pass the cam portions 52 they contact with the undersides of the detents 1 7 and support the detents until the carriers 33have been moved far enough to carry the coins beyond the front ends ofthe steps 36. whereupon the coins will pass through the slots 35 andopenings into the drawer and the detents 4:7 will fall until their booksas contact with the upper sides of the pushers 3 W hen the pushers 33are released they will be returned to their normal positions by thesprings 33, and when they reach such position the detents 47 willgravitate to their normal positions.

A follower is mounted upon each stack of the articles 2i, and carries asign 55 hearing the word Empty. hen all of the articles 21 in any of thecompartments 12 have been sold, the follower 54: will rest upon theflange portions 31 with the sign in front of the opening 3 registeringwith the empty compartment.

The distance that the stops 36 extend across the slots 34: depends uponthe diam eter of the coin representing the price of the articles Lit,and this distance is such that the stops 36 will support a proper coinand thus permit the actuation of the pusher-s 33 while a smaller coinwill pass freely through the slots 3 and openings 32 into the drawer Allparts of the machine are made of metal, and the casing, article carrier,front 5, top 14-, door 17, and partition 23 are preferably made ofaluminum. If desired the machine may be used for vending articles otherthan soap.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation of the vending machine will be readily apparent tothose skilled in the art to which it appertains. While I have describedthe principle of operation of the invention, together with the devicewhich I now consider to be the best embodiment thereof, I desire to haveit understood that the device shown is merely illustrative, and thatsuch changes may be made therein when desired as are within the scope ofthe invention as claimed.
